Is my dog pining for his big brother ?

There is no doubt that dogs can pine for their companion of a long time. I didn't notice this much when we lost members of our small pack because they probably didn't miss those we lost as there were always others around. However, when we lost our second last Basset (of our own line), who just happened to be litter mates, the brother was totally lost. But he'd never lived as the only dog his whole life and much as he was exceptionally close with his sister, I believe it was more about finding himself on his own, as anything. And yes, when we took him out for his walks, I was very concerned to see him adopting a quite aggressive stance towards any dog who approached him. I think, on reflection that he'd always relied on the others to take care of that sort of thing. When he found himself on his own, he felt very vulnerable and yes, lacking in confidence. It was tragic to see a Basset like this! And actually, much as it took about 4 months before we were able to bring a new friend in to be with him, I set about finding one almost immediately. By that time he had started to settle down again although we had to take him everywhere with us, or not go if we couldn't. And fact is, he didn't want much to do with the puppy we bought in in any case. That might be because we didn't go for another Basset, but a Whippet. And I have to say, she didn't show any sign of pining for him, when we lost him about a year later. We did get another Basset at that point however!!!

However, each situation is unique and you have to decide whether he is going to settle down and eventually quite enjoy being the only dog at home, or not. And just know, bringing in another dog may not work if the personalities are different. I'd consider getting a female actually although obviously if your Lhasa is entire, she'll need to be spayed before her first season (or he'll think all his Christmasses have come at once!).

I'm so sorry for your loss because it's bad enough, without having the dog left behind upset like this. Actually having another puppy might help fill the huge hole you have right now.

Our 17 yr old Collie X died 2 years ago on November 2. And my dogs missed her dearly.

A year later 30 August 2011 my own dog who was 11 died. Our Collie missed her, he would sleep with her and they would rest each other's heads on each other. A few months later we got a Husky, who I think has helped calm the Collie down. Allthough she likes to play with him a lot.

I can't believe it'll be nearly a year since my dog died. And 2 yrs since our elderly dog passed.

How heartbreaking it was for them to die a few months apart(give or take a year).

Your dog will get better and realize that he won't come back, but don't worry.

Dogs most certainly DO grieve when they lose their companion dog. I've experienced this countless times over 37 years of sharing my life with my beloved Pointers.

Your Lhaso will accept another companion when you feel the time is right to introduce one. I always do so quite soon after the death of a dog and this has worked for me and and mine.

Dogs have NO concept of having a "BROTHER". Getting another dog would be YOUR decision.

WERE inseparable

WERE together

Yes. He does want his brother. But they do get better after a while. Just like us humans. We will sadden when our siblings die, but we manage.

Yes he probably missed him because he's used to having him around
